3 Claims. (01. 248276) This invention relates to mirrors for motorveparts throughout the several views and the folhicles or the like ofthe kind illustrated in lowing specification.

The joint isespecially simple to produce in either die casting or sand casting,resulting in low production costs. It presents an attractive appearanceof a streamlined character of particular advantage in fast movingvehicles.

In Fig. 7 which corresponds to Fig. 3 is shown a modified method ofassembly to the joint which is the same as the one described andillustrated in Figs. 1 to 7, but the ball l5 and shank 16 are made partof the mirror ill, while extension l2 and terminal I3 are part of post Il. The connections are thus reversed without a change in the joints. Thesame reference numbers as used heretofore are used in Fig. 7.

In Figs. 8 and 9 is shown a modification of the joint itself. Theclearance recess for the shank [6 below the ball E5 of the post I4 isentirely in a half i'ia of the joint as shown at 24a. In all otherrespects, the joint is the same as the one previously described and thesame reference numbers are used.

The modifications are introduced solely for the purpose of showing otherforms of joints still within the principles of the invention. It

- is obvious therefore that various other changes in form, proportionsand minor details of construction may be resorted to without departingfrom the principles or sacrificing any of the advantages of theinvention as defined in the appended claims.

What I claim as new is:

1. In an adjustable mirror assembly for motor vehicles including amirror and a supporting post, a flared shank extending from one of thesaid parts terminating in a ball of larger diameter than the shank, thesaid post terminating in a small cylindrical extension having anenlarged end, a clamping element connecting the said ball and extensioncomprising two halves forming a substantially cylindrical member roundedat one end and fiat at the other, the said rounded end adapted toreceive within it the said ball and having a flared opening to provideclearance and movement for the said shank, the said flat end adapted toreceive within it the said extension and enlarged end, and a screwadapted to draw the halves together and relatively movable upon the saidball and extension with enlarged end to permit adjustment of positionsof the said mirror and post, the said extension being rotatable in aplane of the longitudinal axis of said clamping element.

2. In an adjustable mirror assembly for motor vehicles including amirror and a supporting post, a cylindrical extension to the mirrorhaving an enlarged end, the said post terminating in a small flaredshank carrying a larger ball, a clamping element connecting the saidextension and. ball comprising two halves forming a substantiallycylindrical member, one end of which being adapted to receive within itthe said ball and having a flared opening common to both halves toprovide clearance and movement for the said shank, the other end of thesaid member being adapted to receive within it the said extension withits enlarged end, and a screw adapted to draw the halves together andmaintain them in movable relation upon the said ball and extensions topermit adjustment of positions of the said mirror and post, the saidextension being rotatable in a plane of the longitudinal axis of saidclamping element.

3. In an adjustable mirror assembly for motor vehicles including amirror and a supporting post, a cylindrical extension to the mirrorhaving an enlarged end, the said post terminating in a small flaredshank carrying a larger ball, a clamping element connecting the saidextension and ball comprising two halves forming a substantiallycylindrical member, one end of which being adapted to receive within itthe said ball and having a flared opening in one of the halves only toprovide clearance and movement for the said shank. the other end of thesaid member being adapted to receive within it the said extension withits enlarged end, and a screw adapted to draw the halves together andrelatively movable upon the said ball and extension to permit adjustmentof positions of the said mirror and post.
